Detailed ways:

As shown in Figures 1-4, a fully automatic valve stem end grinder is characterized in that the valve stem end grinder consists of a blanking rack 1, a transfer arm 2, a clamping positioning seat 3, and a grinding device 4. The discharge trough 5, the machine body 6 and the automatic circuit system are composed. The blanking frame is provided with a feed trough composed of a plurality of straight rods, and a thread adjustment mechanism is provided between the plurality of straight rods to realize adjustable width. In order to adapt to blank materials of different sizes, the lower end of the blanking frame 1 is provided with longitudinal and horizontal chute, the end of the blanking frame 1 is connected to the conveying arm 2, and the conveying arm 2 is provided with a lifting mechanism 21. The raw material is sent to the clamping positioning seat 3 through the lifting mechanism 21 of the conveying arm 2. After that, the lifting mechanism 21 returns to its original position and is ready to receive another blank material. The blank material moves to the grinding device 4 to grind the end surface of the workpiece. The grinding device 4 includes a grinding wheel 41, a motor 42 and a transmission wheel. After the grinding is completed, the positioning seat 3 is clamped to release the blank material, and it moves to the transmission arm. 2 receives the next blank material, and the discharge trough 5 is arranged under the clamping positioning seat 3 to receive the dropped blank material and send the blank material out.

The grinding device 4 is also provided with a grinding wheel wear detection device 43 and a grinding wheel wear compensation device 44 , and the grinding wheel wear detection device 43 is arranged beside the grinding wheel 41 .

The moving power device of the clamping positioning seat 3 can be driven by an oil cylinder or driven by a motor and a gear (not shown in the figure). The clamping positioning seat 3 is driven by an oil cylinder to realize the process of receiving the blank material and feeding the knife to realize the grinding process.

The grinding wheel wear detection device 43 includes a detection element 45 and a transmission bracket 46 , and the detection element 45 is arranged on the transmission bracket 46 .

The detection element 45 can be an infrared emitting tube and a receiving tube. When the transmission bracket 46 moves back and forth, the detection element 45 can detect multiple times, and when it is determined that the grinding wheel has wear and tear, the amount of wear of the grinding wheel is converted into a movement command and transmitted to the grinding wheel wear compensation device 44 .

The grinding wheel wear compensation device 44 includes a grinding wheel adjustment mechanism and a detection feedback element, and the adjustment mechanism is connected to the bottom of the grinding device 4 . After receiving the movement command from the wheel wear detection device 43, the grinding wheel adjustment mechanism controls the movement of the grinding wheel adjustment mechanism, and detects the displacement by the detection feedback element. Feedback to the grinding wheel adjustment mechanism for displacement adjustment.

The grinding wheel adjustment mechanism is a gear chute, and the gear chute is arranged at the bottom of the grinding device 4 .
